; This macro allows you to use a fixed machine location for a tool change and probe. It works by
; probing twice, once to capture the position of the tool you're changing away from, and again to
; set the adjusted WCS offset of the tool you're changing to.

; Using the macro in practice:
; 1) Insert an M6 tool change command in your program, which will pause cncjs and allow you to
;     execute this macro.
; 2) The router retracts to a safe height and moves to a pre-defined location for tool changes and
;     probing, then pauses.
; 3) Turn off your router, set up your probe, and continue. This will probe to capture the position

Title: A bit beyond Git basics: Q&A Date: 2013-10-04

Q: How do I create a new branch?

git branch <my-branch>

This creates a new branch that points to whichever commit you're currently on. Remember though that it doesn't change your current branch – it only creates a new one.

Q: How do I switch to another branch?

// Run with `node --harmony coro.js`

"use strict";

const Promise = require('bluebird');

// Takes a function*, `g`, that yields promises.
// Returns a promise that resolves to `g`'s eventual return value.
var coro = function(gStar) {
  const pending = Promise.pending();

A bit beyond git basics: Q&A edition

Questions:

• How do I create a new branch?
• How do I switch to another branch?
• How do I create and switch to a new branch in a single command?
• I've made whatever changes I want on my new branch. How do I merge these changes back into master?
• After merging, git told me that I made a "fast-forward merge." What does that mean?
• After merging, git told me that there were auto-merge conflicts. What does that mean and how do I fix it?
